Abstract
The colossal appeal of eco-friendly and sustainable concrete has made researchers find a substitute for Portland cement concrete. Therefore, geopolymer is an innovativeand environmentally beneficial binder material that was developed to reduce Portland cement's harmful environmental consequences. Also, it is seen that certain properties are shared by both Portland cement concrete and geopolymer concrete including brittleness. Hence, fibres are added to surpass the matrix’s brittleness and improve the tensile, and flexural strength as well as stiffness of concrete. Based on previous research, the primary focus of this study is on the impact of different fibre types on the long-term mechanical performance of geopolymer composites. It also examines the usage of potent pozzolanic metakaolin, which is often added to concrete to increase its mechanical qualities or serve as an alternative for cement. In addition, this study investigated the literature on the effects of fibre characteristics with variable volume proportions on the mechanical strength of metakaolin-based geopolymer concrete. It is seen that geopolymers improved characteristics after fibre addition has opened the door to more research into the material's potential use in various applications.
